JAMES R. BLAKEMORE, OF MURFREESBORO, TENNESSEE, ASSIGNOR TO GREEN IB.

SAWYER, OF MURFREESBORO, TENNESSEE.

EGG-TESTER.

Application filed April 8, 1919.

To all whom it may concern:

Be it known that 1, JAMES R. BLAKEMORE, a citizen of the United States, residing at Murfreesboro, in the county of Rutherford and State of Tennessee, have invented cer tain new anduseful Improvements in Egg- Testers, of which the following is a specification.

This invention relates to improvements in devices for testing eggs, and has for one of its objects to simplify and improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a device of this character of separable parts, whereby impaired or broken parts may be readily renewed without discarding the remainder of the device.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction, accompanied by elements and arrangement of parts which will be more fully described in the following specification and set forth with particularity in the claim appended hereto,

Figure 1 is a perspective view of the improved device,

Fig. 2 is a vertical longitudinal section enlarged, and,

Fig. 3 is an enlarged transverse section on the line 33 of Fig. 2.

The improved device comprises a tubular chimney member 10 of sheet metal open at both ends and with a protecting hood 11 at tached at the upper end. The member 10 is designed to bear over a light such as a lamp or the like, the latter being indicated conventionally at 12.

Formed to one side of the member 10 at a point about opposite where the flame of the lamp will occur is an opening indicated at 13. A hood device represented as a whole at 14 is attached by suitable fastening devices 15 to one side of the member 10, and is provided with an opening indicated at 16 slightly larger than the opening 13 and in transverse alinement therewith when the member 14 is attached to the member 10. Engaging through the opening 13 of the member 10 is a tubular sight member 17 having an outstanding bead 18 at one end, the

bead forming a flange or stop to limit the movement of the member 17 in one direction. I The bead 18 bears between the confront ing portions of the members 10 and 1 1 as shown in Figs. 2 and 3, the thickness of the bead thus holding the portion of the member 14 immediately surrounding the opening 16 spaced away from the member 10 as indicated in Fig. 2. Two of the fastening devices 15 will be located relatively close to the openings 13 and 16, so that when applied they will compress the portion of the member 14 immediately surrounding the opening 16 against the outer face of the head 18, and thus support the latter in position and likewise support the tubular sight member 17 in place.

Located within the bead member 18 is an annular packing or compressible device 19, of leather, rubber or the like, the inner edge of the member 19 extending slightly into the opening in the member 17 as disclosed in Figs. 2 and 3. The member 19 will be compressed into the bead member 18 and will be held by friction, while at the same time the pressure applied by the fastening devices which hold the inner walls of the member 14: compressed against the bead 18 will likewise compress the member 19 and assist in holding it in position.

One end of the egg to be tested is inserted within the opening of the member 19 and thus disposed opposite the flame of the lamp 12, so that the presence or absence of growing matter within the egg will be revealed in the ordinary manner.

The parts of the improved device are constructed of sheet metal, preferably of tin with a highly polished surface. The improved device is simple in construction, can be inexpensively manufactured, and the parts readily separable for repairs, or for the removal of broken parts without discarding the remainder of the device.

Having thus described the invention what is claimed is A device of the class described comprising a tubular member having a lateral opening and adapted to receive a light transmitting medium, a sight tube engaging in said opening and having an outwardly projecting annular bead bearing against the outer face of the tubular member, an annular member of yieldable material engaging in said bead, a holding member including a plate having an opening corresponding to 5 the opening of the tubular member and bearing against the bead of the sight tube, and means for connecting the plate to the tubular member and compressing the plate against the bead and holding the sight tube and yieldable member in position. 10

In'testimony whereof I atfix my signature thereto.

JAMES R. BLAKEMORE.
